# package.el-based emacs packages

## FOR USERS
#
# Recommended way: simply use `emacsWithPackages` from
# `all-packages.nix` with the packages you want.
#
# Possible way: use `emacs` from `all-packages.nix`, install
# everything to a system or user profile and then add this at the
# start your `init.el`:
/*
  (require 'package)

  ;; optional. makes unpure packages archives unavailable
  (setq package-archives nil)

  ;; optional. use this if you install emacs packages to the system profile
  (add-to-list 'package-directory-list "/run/current-system/sw/share/emacs/site-lisp/elpa")

  ;; optional. use this if you install emacs packages to user profiles (with nix-env)
  (add-to-list 'package-directory-list "~/.nix-profile/share/emacs/site-lisp/elpa")

  (package-initialize)

        Request.el is a HTTP request library with multiple backends. It supports
        url.el which is shipped with Emacs and curl command line program. User
        can use curl when s/he has it, as curl is more reliable than url.el.
        Library author can use request.el to avoid imposing external dependencies
        such as curl to users while giving richer experience for users who have curl.
